Pinellas deputies said the younger Perry refused to calm down after bar patrons taunted him about his father's link to the case of the 34-year-old woman who has been missing for five weeks.

According to the Sheriff's Office, 21-year-old David Perry was harassed by patrons at Cuso's Club and Cantina, 2405 Gulf Blvd., about 12:40 a.m. Friday.

When deputies arrived, two friends were trying to calm Perry down. But Perry continued to create a disturbance, deputies said, yelling and cursing at those in the bar. He was then arrested.

Rothwell has been missing since March 12, the day she intended to break up with her boyfriend, the elder David Perry, 47. She wasn't reported missing until days later, during which time deputies said her boyfriend abruptly returned to New York. To this day he has refused to even speak with investigators, according to the Sheriff's Office.

Last week Rothwell missed graduation with the St. Petersburg College police academy's 177th class. At a vigil Wednesday, Detective Michael Bailey said he is treating the case as a homicide.

The younger David Perry was released Friday from the Pinellas County Jail on his own recognizance.
